They perform the Boolean functions Y = A ⊕ B or Y = AB + AB in positive logic. A common application is as a true/complement element. If one of the inputs is low, the other input is reproduced in true form at the output. If one of the inputs is high, the signal on the other input is reproduced inverted at the output.

EXCLUSIVE-OR =1 These are five equivalent exclusive-OR symbols valid for an ′ALS86 or ′AS86A gate in positive logic. Negation may be shown at any two ports. LOGIC-IDENTITY ELEMENT = The output is active (low) if all inputs are at the same logic level (i.e., A = B). 2 EVEN-PARITY ELEMENT 2k 2k + 1 The output is active (low) if an even number of inputs (i.e., 0 or 2) are active. POST OFFICE BOX 655303 ODD-PARITY ELEMENT • DALLAS, TEXAS 75265 The output is active (high) if an odd number of inputs (i.e., only 1 of the 2) are active.
